Subject: headers: move module_bug_finalize()/module_bug_cleanup() definitions into module.h
X-Git-Tag: upstream/snapshot3+hdmi~18577^2~69
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0d9c25dde878a636ee9a9b53923569171bf9a55b;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

headers: move module_bug_finalize()/module_bug_cleanup() definitions into module.h

They're in linux/bug.h at present, which causes include order tangles.  In
particular, linux/bug.h cannot be used by linux/atomic.h because,
according to Nikanth:

linux/bug.h pulls in linux/module.h => linux/spinlock.h => asm/spinlock.h
(which uses atomic_inc) => asm/atomic.h.

bug.h is a pretty low-level thing and module.h is a higher-level thing,
IMO.
